1. Reproduction
It can be propagated by seeds and cuttings. Seed propagation was sown in spring and planted for 2-3 years, while cuttage propagation was carried out in the spring season of high temperature and humidity and planted for 1-2 years. In spring, holes were opened according to the row spacing of 3m × 3m, and 1 seedling was planted in each hole, compacted with soil and watered.
two。 Pruning
In the young tree stage, the skeleton of the cultured tree was mainly formed by light pruning, and the central elongated branches and the main and secondary branches were selected for moderate or heavy truncation, the rest of the branches were lightly truncated, and the weaker branches in the middle and lower parts were retained. In the full fruiting period, the fruiting branches were renewed, diseased, weak, withered, crossed and overlapping branches were cut off, and the method of opening "skylight" was adopted to cut the overcrowded backbone branches, so as to solve the problem of ventilation and light transmission, and keep the balance between branches and fruit.
